Overclockaholics Forums - 1HP Rotary Cooler

Hello everyone,

In fact it's my first serious unit. It took a lot of time to build this, but it wasn't wasted time ;)

Just an ordinary, quite strong SS. I'm pretty satisfied with the results (-41C @ 250W, -46C @ 180W, -54C @ idle). Maybe it can be tuned a little better (it also depends on where K-type probe is located, I've drilled small hole on the top of evap, bcoz for now I'm mostly interested in overclocking, not the lowest temperature ;) ). I've tested it few days ago, and on E8400 @ 5,2GHz 1,8v there was something like -48C what is nice ;)
